A terminal reader, ipx; the server is ipxd (#437)

ipx-tui (crates/tui) is iPX's reader in ratatui: your feeds, a feed's
items, an item's text as plain text, read and flagged as on the page,
through the API with an API token. It installs as `ipx`, so the daemon's
binary is now `ipxd`: the Dockerfile, release script, tests and every
doc and message that names its commands follow.

Naming the binary ipxd alone renamed its crate, and with it every log
target (ipx::scan became ipxd::scan): the default filters are ipx=info,
so nearly every line would have been dropped and the dashboard's queries
on the targets gone blank. The daemon's code is now a library still
called ipx, under a five-line ipxd main.rs, and the targets are as they
were.

ratatui is taken without its default features: 32 new packages in place
of 78.
